PCF2123U/5GA/1,015 Overview
In 12 terminations, a transmission line is terminated with an impedance-matched RTC module.2V voltage is present on this electronic component.The output frequency should not exceed 0.032MHz.A total of 1.1/5.5V power supplies are required to operate it.An input signal is received by 1 timers, which output a signal after a preset time.In this case, the supply voltage reaches 4.2V (Vsup).The type of uPs/uCs/Peripheral ICs for this electrical real time analog clock is TIMER, REAL TIME CLOCK.Normal operation requires a supply voltage (Vsup) above 1.8V.Keeping the operating temperature below 85°C is recommended.
